ABRADING-MACHINE.

Application filed February 23, 1909.

To all whom it may concern:

Be it known that we, FRANK C. RowELL and J AMEs L. NOLAN, citizens ofthe United States,.residing at Ilion and at Mohawk, respectively, in thecounty of Herkimer and State of New York, have invented certain newand'useful Improvements in Abrading- Machines, of which the following isa specification, reference being had therein to the accompanyingdrawing.

Our invention relates to an improved abrading machine, and we declarethe following is a full, clear, concise and exact description thereof,sufficient to enable one skilled in the art to make and use the same,reference being had to the accompanying drawings in which like referencecharacters refer to like-parts throughout.

While we refer to the invention as an abrading machine, we mean toinclude in that term the definition of a machine which may be used forforming articles of irregu lar shapes either of wood or any material andfinishing and polishing them according to any given pattern.

The machine we have devised comprises means whereby the article to beworked may be moved sidewise across the entire width of the abradingsurface, and at the same time it may be revolved so that all points willbe subjected to the same abrading surface successively. It may be movedalso longitudinally so that the work will be done from end to end of thearticle, and during these different operations the mechanism is capableof tilting so as to allow for any irregularities in the pattern.

The device is shown in the drawings as having a gun stock mounted forfinishing, and it will be seen that the device carries a pattern stockwhich rests upon the wheel, the work itself being supported at one endof the pattern stock and resting upon the abrading surface, so that theirregularities of the pattern will be imparted to the work which isbeing finished, and the operation thereon will correspond to the patternwhich it will be seen is necessarily somewhat smaller than the articleitself.

In the drawings, Figure 1 is a plan view of the device; Fig. 2 is a sideView; Fig. 3 is a side view from the opposite side, with certain middleportions cut out, and Fig. 4t is an end view at the head of the machine.

ferent parts of the device are supported on a table shown in general byA, one end of which is supported by legs B so formed as to provide aclearance crosswise of the table at one end, as seen in Fig. 3. Fromthis end the table extends lengthwise of the machine for supporting thepattern carrying wheel, and being further extended to support a shaftwhich carries the abrading member, which is here shown in the form of abelt. Referring now to the other end of the table, parallel tracks arearranged crosswise the head of the table and shown by l and 2. A bar orframe indicated by 3 may be secured to the opposite portions of thetable, one being shown by 3 on which is supported a fixed block 4 havinga threaded aperture. On the tracks 1 and 2 is mounted a frame orcarriage 5 comprising parallel side members which rest on the tracks andtransverse members 6 for connecting the two and supporting parts of themechanism. The track members are longitudinally cut out at the lowerouter portion, leaving an overhang 7 and the track .is provided withfingers 8 extending downward and beneath the overhang to keep the tablefrom displacement, but to permit its moving from end to end of thetracks crosswise of the table. The track has rail 9, the carriage havingcorresponding grooves. At one end of the table and on the carriage isfixed a stud or block 10 apertured to register with the apertures of thefixed block 4 on the table.

A screw shaft 11 is mounted in the two blocks 4 and 10, beingscrewthreaded through block 4 and headed to block 10, by the revolutionof which the carriage is moved to and fro on the table. This to and fromovement is effected by the following described parts. Supported on thecarriage are two hangers or journal boxes, one near each end and shownby 15 and 16. At the upper part of these hangers is journal'ed andcarried the shaft 17 which extends lengthwise of the carriage. Near oneend of the shaft is fixedly mounted power pulley 18 through which poweris transmitted from suitable source to operate different parts of themachine to be described. At the end of the shaft is mounted a gear 20and adjacent thereto is a gear frame 21 loosely hung thereon whichcarries at one point a gear 22 and at another point a train of gears 23and 24. At the end of the threaded shaft 11,

of the gear frame. It will thus be seen that the revolution of shaft 17through'the gears mentioned turns the threaded shaft 11 andreciprocatesthe carriage. This gear rackor frame is shifted by means ofa lever 26 which consists of a bell crank 27 pivotally mounted on thecarriage, having a handle at one end, the other end being connected .toa rod 28. The other end is pinned or otherwise attached to the gearrack, so that the reciprocating of the lever handle pushes or draws therod 28 and shifts the gear frame. Two pins 29 and 30 are mounted on thetable at about the extremities of the movement of the carriage, withwhich the lever handle contacts at either end to operate the levermechanism and swing the gear rack for reversing of the table.

The main shaft 17 extends the entire length of the carriage and beyondits ends to carry the mechanisms as stated. It passes through thejournals in hangers 15 and 16, but it is supported in those journals bysleeve hangers 33 and 34. The journals are bored larger than the size ofthe shaft and the sleeve hangers fit in said boresand are themselvesbored for the shaft. These sleeve hangers have depending portions 35 and36 which in'turn support other depending parts and support certainsuperposed parts. The de ending parts. consist of two hangers 37 an ,38which at the lower ends are bored to carry shaft 39 which extendsoutward on one side of the machine and at one end of the carriage aboutthe distance of shaft 17 as will be seen from Fig. 4. It willthus beseen that the sleeve hangers 33 and 34 and the depending. hangers 37 and38 being all supported on the shaft 17, all the entire structuresupported by or on the sleeve hangers may tilt to and fro so that thework tobe finished may rise or fall according to the outlines of thepattern. At the end of shaft 39 is mounted gear 40 and at the end of themain shaft 17 is'gear 41, the two meshing. The shaft 39 also carries agear 43, and the power shaft also has a gear 44. A bar 45 is mounted onthese two shafts and carries a gear 46 which is intermediate of gears 44and 43, so that the revolution of power shaft 17 by one or the otherconnection with shaft 39 rotates the latter shaft in either direction,which is governed by the following described mechanisms.

Gears 41 and Y44 have laterally projectingclutch with one or the othergear actuates one or the other connections with the shaft '39. o Thisclutch is actuated by a lever 51 pivotally'mounted on arm 52 mounted onthe carriage and has attached thereto a belt 53, one-end at each side ofthe pivotal bearing, which belt passes around a cylindrical member 54mounted on the carriage and having a pm 55 projecting laterallytherefrom over the carriage which moves the work longitudinally andwhich has two pins 56 and 57 so that the movement of the carriage to andfro by actionof said pins alternately on pin 55 rotates the cylindricalmember and shifts the lever to and fro.

Suitably connected to the lower part of the sleeve hangers 33 and 34 isframe 60 comprising side and end pieces which are adapted to support forlongitudinal movement therein afeed carriage, This carriage consists ofa base 61 which supports hangers 62 and 63, through which extends, beingmounted in proper journals, the shaft 65. The sleeve hangers 33 and 34also support the hangers 66 and 67 between which is mounted a worm gear68, the mounting of said worm gear being onshaft 65 and being suitablypositioned between the hangers 66 and 67 by sleeve or spacing rings 69,one on each side of the worm gear. The shaft 65 is splined through theworm gear 68 and the spacing rings so that it may play freely lengthwisetherethrough, butreceive power from the worm gear. The carriagejwhichmoves the work longitudinally to and fro and which carries the shaft 65is moved to and fro by means of a rack 72 carried on the under partthereof with which gear 73 carried on shaft ,39 ,meshes,so that therevolution of the shaft 39 inone direction or the mounted on theshaft'17' and has clutch teeth at one end. At 76 is shown a clutchsplined on the shaft 17 vprovided with teeth to engage the worm andthrow it into action when required' This clutch is operated by means ofa lever 77, at one end engaging a peripheral cutout in the clutch and atthe other end terminating in a handle and being piv- 'oted at a givenpoint on the tilting table by action of which the gear is thrown in orout of action. V

The hangers 62 and 63 support at the top an overhanging arm 80 whichextends out over the pattern and over the work and-has adjustableslidably connected member 81 secured with loops and thumb-screws 83therein and having at the end of its ofiset portion 85 an adjustingscrew 86 to engage and support one end of the material to be worked. Theshaft 65 bears at one end against the pattern 90, the other end ofthepattern being suitably supported'in a carrier 91 to allowlongitudinal adjustment, the other end of the carrier supportingthe'material to be sw et 3 finished. All these connections areadjustable longitudinally. They are also adjustable transverse the axisby thumb-screws 93 properly positioned to effect exact positioning ofthe several parts. On the table are mounted brackets 95 which haveadjustable journal boxes 96 supported on screws 97 mounted in the tableand which have at one end a worm gear 98 which meshes with a worm 99-suitably mounted on a shaft 100 which is turned by means of wheel 101, adog 102 being provided on the table to engage with ratchet teeth on thewheel 101 to hold the same in given position. It will be understood thatthe bracket and adjustable j ournal boxes are provided on each side withthe same adjustment, the shaft 100 extending from one side of the tableto the other. The journal boxes carry shaft 103 which supports a patternwheel 10 1 on which the pattern rests during its ,work. At the end ofthe table is mounted a pair of brackets 107 and. 108* which support ashaft 109 which carries power pulley 110. It will be understood that thepulleys 110 and 18 may re ceive their power from a common shaftingabove. The shaft 109 carries an abrading member 115 which in thisinstance is shown as a belt provided with a properly prepared surfacebut may beof any suitable character or form and which passes over thewheel or pulley 116 at the upper end and at the lower end passes over awheel 118 which is carried on the shaft 119, each end of which issupported in an adjustable ournal box 120 supported in proper foundation121. This foundation block is mounted dovetail in base 122' so that whenthe parts are loosened the foundation may be slid out and a new abradingbelt put in place. The shaft 119 is supported at each end in such ajournal box so that the belt may be properly adjusted at each edge.

It is thus seen that the invention, illustrated in a single form,includes a laterally movable carriage, a tilting frame mounted thereon,a carriage movably mounted in the frame and carrying a work shaftrelative to which the latter carriage is movable.

By the use of this machine, having a pattern and pattern-wheel togetherwith a suitable cutting, grinding, abrading or polishing member, ofwhatsoever kind and for whatsoever work may be desired, an article maybe worked down to any form, according to the pattern, and toany finish,being rotated on its center, moved lengthwise and shifted sidewise fromone edge to the other of the abrading member which may be, of course, ofany given width, one portion for instance, being coarse and anotherfine, or of two or more parts with different means for different kindsof work, as indicated by 180, 131 and 132, which represent differentabrading surfaces.
